Here are some questions about the mask we have collected which you may be interested in.

Why mask is important for covid?

The virus itself cannot exist independently but exists in the droplet and aerosol state droplet nucleus. The mask filters droplets and droplet nuclei to achieve anti-virus effects.

1. Diameter> 10 microns: Even the worst degreasing gauze mask can filter more than 80% of this large particle droplet.

2. Diameter <0.1 microns: This tiny droplet nucleus is easily filtered by the electrostatic effect. The filter layer of the mask mostly uses electrostatic adsorption materials (such as polypropylene), but washing with water will reduce the adsorption effect.

3. Diameter ≈ 0.3 microns: This is the most difficult to filter, so the mask testing standard uses 0.3micron sodium chloride. As long as the test passes, filtering other particles is not a problem.

82% of the droplet nuclei have a diameter in the range of 0.74~2.12 microns.

1.Disposable medical surgical mask, filtering droplet effect is above 80%.

2.The filtering effect of ordinary disposable medical masks is above 70%.

3.KN95 dust mask can filter more than 95% of sodium chloride particles; KN90 can filter more than 90%.
